Finally, a real scientific controversy: arsenic in DNA

ArsTechnica: We spend so much time discussing manufactured controversies about science that it's a bit refreshing to be able to report on a real one. And one has been brewing since late last year, when Science released a report that suggested that researchers had forced bacteria to evolve to the point where they no longer simply tolerated arsenic, but incorporated it into their DNA. The publication quickly attracted criticism on a few blogs that were written by scientists, leading mainstream reporters to dig into matters. Now, the scientific community is having its say in the pages of Science, with eight separate technical comments on the work.

Won't be truly controversial until you tie it somehow to religion or humans ruining the planet.

No, sometime last year a new type of bacteria was discovered that arsenic had replaced a protien commonly found in every other living organisms DNA and they were just able to replicate that in the lab. Which is raising controversy that did life spring up twice on earth? or is it a evolutionary step being witnessed in realtime.
